c++实现单链表删除重复节点

好的，以下是 C 语言实现单链表删除重复节点的代码：

#include <stdio.h>
#include <stdlib.h>

typedef struct Node {
    int data;
    struct Node *next;
} Node;

void deleteDuplicates(Node *head) {
    Node *current = head;
    while (current != NULL) {
        Node *runner = current;
        while (runner->next != NULL) {
            if (runner->next->data == current->data) {
                Node *temp = runner->next;
                runner->next = runner->next->next;
                free(temp);
            } else {
                runner = runner->next;
            }
        }
        current = current->next;
    }
}

int main() {
    Node *head = (Node *) malloc(sizeof(Node));
    head->data = 1;
    head->next = (Node *) malloc(sizeof(Node));
    head->next->data = 2;
    head->next->next = (Node *) malloc(sizeof(Node));
    head->next->next->data = 3;
    head->next->next->next = (Node *) malloc(sizeof(Node));
    head->next->next->next->data = 2;
    head->next->next->next->next = NULL;

    printf("Before deleting duplicates: ");
    Node *current = head;
    while (current != NULL) {
        printf("%d ", current->data);
        current = current->next;
    }
    printf("\n");

    deleteDuplicates(head);

    printf("After deleting duplicates: ");
    current = head;
    while (current != NULL) {
        printf("%d ", current->data);
        current = current->next;
    }
    printf("\n");

    return 0;
}

希望这个代码能够帮到你！
